Application January 10, 1935, Serial No. 1,174

1 Claim. (Cl. 20-55) This invention relates to supplemental sash for windows or similar apertures, and more especially it relates to improved window sash applicable to storm window and fly screen construction. It is within the purview of the invention to use the invention interchangeably for storm win dows or flyscreens, although but one form of the invention is shown anddescr ibed.

The chief objects of the invention are to provide supplemental window sash comprising upper and lower members, which members may be easily mounted, dismounted, or interchanged from inside the building; to provide ready application of the sash to an opening not especially constructed therefor; to provide weatherproof mounting of the sash about the margins thereof and at the juncture of the upper and lower sash, in the middle of the opening; and to provide such construction at the juncture of the upper and lower sash as not seriously to re- 0 duce the transparent area within the sash. Other objects .will be manifest.

Of the accompanying drawing,

Figure 1 is an inside view of an ordinary window frame without sash, and the supplementary window sash mounted therein;

Figure 2 is a section on the line 2-4 of Figure 1;

Figure 3 is a section, on a larger scale, on the line 3-3 of Figure 1; and

Figure 4 is a fragmentary elevation, on a larger scale, of a lower corner of the upper supplementary sash and adjacent window frame.

Referring to the drawing, I0 is an ordinary window frame, which, for clearness of illustration, is shown without the ordinary window panes and sash therein, Said window frame includes the usual sill H at the bottom thereof, and a flat moulding I? about the sides and top of that portion thereof that is disposed outermost when mounted in a building aperture.

Mounted upon theoutcr side of window frame It is a supplemental frame it that is rectangular in shape and rests upon the sill H, the sides and top of the supplemental frame being so shaped as to fit within the moulding l2, and to rest against the outer face thereof. The supplemental frame is removably held in place by a plurality of clips l6, it that are pivotally mounted upon the outer face of the moulding l2 and are mov able angularly over an adjacent edge of. the supplemental frame. The inner marginal face of the supplemental frame it is formed with an inwardly extending flange it at its outer edge. The inner lateral face of the supplemental frame is formed on all four sides with a longitudinally extending groove It" and longitudinal tongue or rib l4.

Mounted within the supplemental frame it in abutting relation with flange il thereof is an upper sash ll and a lower sash it, each of said sashes being provided with a window pane i9. Said sashes substantially abut the inner marginal faces of the said frame, and upper sash I1 is formed on three sides with a longitudinally extending tongue H and groove l'l which tongue and groove are complemental to groove li and tongue ll of the supplemental frame It and snugly interflt therewith. Similar tongues l8 and grooves l8 are formed on three sides of lower sash l8 and similarly interflt with the tongues and grooves of said frame. The adjacent rails of the sashes IT, IS, at the middle of the structure, overlap each other, and have their adjacent lateral faces formed with interfltted, longitudinally extending, complemental tongues and grooves as is most clearly shown at 20, Figure 2. The respective sashes l1, it are retained in frame it by means of suitable latches 2|, 2|, one of which is pivotally mounted upon-each side of the inner face of the sash, and is capable of angular movement to a position behind an inwardly extending flange It on frame It. The surface of flange It may be recessed as shown at 22, 22 to receive the latches M.

The feature of having the interfltting tongues and grooves of the frame and sashes on the lateral fac'es thereof facilitates the mounting and removal of the sashes. It also permits the overlapping of the adjacent rails of the sashes, at the middle of the structure, whereby the transparent area of the window is not seriously reduced. The sashes are mounted and removed from the inside, thus obviating the use of scaffolds or ladders which are required for mounting supplemental sash from the outside and simplifying the procedure of washing the window panes in said sashes. The invention contemplates the provision of a duplicate set of sash l1, l8, which sash will be provided with fly screening instead of window panes, and said duplicate sash maybe easily and quickly substituted for the others.

Modifications may be resorted to without departing from the spirit of the invention or jthe scope of the appended claim which is not limited wholly to the specific construction shown and described.

What is claimed is:

The combination with a window frame, of a supplemental frame adapted to be secured in the 2 amazes opening thereof, and a pair 01' removable sashes mounted in vertical alignment in said supplemental frame, said frame being formed on the rear face of its top, bottom and side members with a longitudinally extending; rearwardly prowith those aforesaid, the top side oi. the lower sash and the bottom side of the upper sash partly overlapping each other, and said overlapping pot tions being formed with interfltting laterally projecting tongues and laterally opening grooves,

each or said sashes being removable from the 5 supplemental frame by lateral movement .of translation'normal to the plane'ot the sash.
